I am running exactly as you did  
curl -XPUT '[http://localhost:9200/\_river/test/\_meta](http://localhost:9200/_river/test/_meta)' -d '{  
"type": "mongodb",  
"mongodb": {  
"db": "test",  
"collection": "es\_test"  
},  
"index": {  
"name": "mongoindex",  
"type": "es\_test"  
}  
}'  
However I am getting the following exception again and again:

{"error":"MapperParsingException[Failed to parse]; nested:  
JsonParseException[Un  
expected character ('m' (code 109)): expected a valid value (number,  
String, array, object, 'true', 'false' or 'null')\n at [Source:  
[B@61f133ea; line: 1, column:8]]; ","status":400}

can you please point out what I am doing wrong? I am completely new to  
ElasticSearch and will appreciate your assistance.
